few limitation for alpha version:
1. MUST be run with ‘-force-opengl’ (use .bat file to start demo)
2. dont work in ‘DirectHMD Access’ mode, only in ‘Extend Display’, due OpenGL, i will try to rewrote all shaders in Cg in future versions.
3. You need good GPU for better fps.
4. no controls for the moment, just sit, look around and relax. turn on good music )
